I APPARATUS FOR TRIMMING THE FINS FROM DIE-FORGED AXLES.

SPECIFICATION forming part of Letters Patent No. 434,068, dated August 12, 1890.

Application filed January 22, 1890. Serial No. 337,752. (No model.)

To all whom it may concern.-

Be it known that l, WoLoorT J. PARMELEE, a citizen of the United States, residing at Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Process of and Apparatus for Trimming the Flash from Die-Forged Axles, of

which the following is a specification.

This invention relates to an improved process of and apparatus for trimming the flash from the collars of die-forged axles.

In a companion application of even date herewith I have described a process of and apparatus for forging axles whereby axles are constructed in which the flash is formed at an intermediate point upon the collars. It is for the removal of this flash by a simple, rapid, and inexpensive process that my present invention is designed.

The apparatus used by me for trimming the flash from the collars does not differ essentially from that used for forging the axles, the machine being the same and the dies being but slightly changed. The machinethat is to say, the bed upon which the dies are mounted and the mechanism for manipulating the diesforms no part of theinvention. The dies and the process of manipulation, which constitute my present invention, will be hereinafter fully described with reference to the drawings, in which Figure 1 is a longitudinal sectional view showing the plunger-die at a distance from the holding-dies, and showing in elevation an axle mounted in position for operation. Fig. 2 is a similar View after the forward movement of the plunger. Fig. 3 is a transverse sectional view of the holding-dies. Fig. 4 is a side elevation of one end of one of the sections of the holding-dies. Fig. 5 is a longitudinal sectional View illustrating a modification.

Like numerals of reference indicate like parts in all the figures.

The holding-die is composed of two sections 1 and 2, the former of which is intended to be stationary, while the latter is intended to be laterally movable. The meeting faces of said holding-die sections are provided with angular recesses 3 to accommodate the square portion of theiaxle at the inner-end of the The recesses in the said holding-die collar.

sections are made of such a size as to permit of a longitudinally-sliding movement therein of the axle. The outer ends of the sections of the holding-die are provided with semicircular or semi-cylindrical recesses 4, which must be sufficiently large to accommodate the entire collar at the inner end of the spindle upon the axle. Y I

5 designates the longitudinallymovable plunger-die, which has a bore or recess 6, of suitable size and shape to accommodate the spindle, the end of said plunger-die being adapted to abut against the outer end of the collar. The outer end of the plunger-die is also beveled, as shown at 7, to aiford room for the flash when the latter is trimmed from the collar. The front ends of the holding-die sections have cutting-edges at 8.

The operation of thisinvention will be very readily understood from the foregoing description when taken in connection with the drawings hereto annexed. When the sections 1 and 2 of the holding-die are separated, the stock or axle is placed between the same, where it is held securely, as shown in Fig. 3, the stock being placed well forward between the dies, with the flash in front of the cuttingedges at the outer ends of the same, as will be seen in Fig. 1 of the drawings. The plunger is now operated or caused to move in the direction of the holding-dies. The spindle will enter the bore of the plunger, and the front end of the latter Will abut against the outer end of the collar and force the axle back between the holding-dies, the cutting-edges of which, by a shearing action, will trim the flash neatly from the collar, which latter is forced into the recesses 4, at the front ends of the holding-dies. When the plunger recedes, the movable holding-die section is likewise caused to recede, and the axle is removed and reversed, or turned end for end, and the operation repeated upon the other end of the axle.

The foregoing operation may be performed while the axle is cold, and is exceedingly simple, efficient, and rapidly performed.

Instead of forcing the axle endwise between the holding-dies, as herein described, the said holdingdies may be constructed to abut against the inner end of the collar and to hold the axle securely against longitudinal move- The latter is then ready for the turner.

ment. In this case the plunger-die, as shown in Fig. 5 of the drawings, is to be provided at its outer end with an'anuularrc ess or cavity of sufficient size to accommodate the collar, as shown at 9 in Fig. 5 of the drawings, and the front end of said plunger-die willlikewise be provided with a cutting-edge 10. I reserve the right to this and to any other modifications which may be resorted to without departing from the spirit of my invention.

Having thus described my invention, what I claim is 1. The combination of the holding and cutting dies, one of which is socketed to receive the spindle of the axle which is to be operated upon, substantially as set forth.

2. In mechanism for removing the flash from the collars of axles, a cutting-die having a recess to receive the collar of the axle to be operated upon, said recess being provided with cutting-edges at its front end, substantially as set forth.

3. In mechanism for removing the flash from the collars of axles, the combination of the holdingdies and a longitudinally-mov- 25 said axle, said holding-dies being provided with recesses to accommodate the collar, and having cutting-edges, as described, in combination with thelongitudinally-movable plun ger recessed to accommodate the spindle and beveled at its front end, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in presence of two witnesses.
